Formula for rhombus: base x height.
Base: 8
Height: 2.5
2.5 x 8 = 20.
Tip: Usually when finding the area of a rhombus there is another length (in this scenario, 4) to try to fool or trick you. It's the length of the slanted side to the right. A rhombus is a square or rectangle when you take the triangle and piece it into the slanted area, so even though it looks like a complicated parallelogram it really isn't.

find the value of x in the triangle, 60°, 60°, 5x
Answers
The value of x in the expression for the angle of the triangle is 12.
What is the value of x in the triangle?The figure in the image is a triangle.
From the image:
Angle 1 = 5x
Angle 2 = 60 degrees
Angle 3 = 60 degrees
Note that, the sum of the interior angle of a triangle equals 180 degrees.
To determine the value of x, add the 3 angles and equate to 180 degrees.
Hence:
5x + 60 + 60 = 180
Collect and add like terms:
5x + 120 = 180
Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120
5x = 180 - 120
5x = 60
x = 60/5
x = 12
Therefore, x has a value of 12.

he height of the triangle is 15 cm and the base is (45-x) cm. If the area of the triangle is 225 cm2, what is the value of x?
Answers
Answer:
x =15
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
We know the area=225 and the base= (45-x) and the height =15
Substituting these into the equation
225 = 1/2 (45-x)*15
225 = 15/2 (45-x)
Multiply each side by 2/15
2/15 *225 = 2/15*15/2 (45-x)
30 = 45-x
Subtract 45 from each side
30-45 =45-x-45
-15 = -x
Multiply each side by -1
15=x
For a club gathering you were having, you bought a total of 50 burgers, and spent $90. You paid $2 per turkey burger, and $1.50 for each veggie burger. Next year, you want to spend the same amount of money on burgers, $90. If the number of turkey burgers is doubled, would you have to cut the number of veggie burgers in half? Explain your reasoning.
Answers
Answer:
No. You would have to cut the number of veggie burgers in more than half.
Explanation:
1. Model the situation with a system of equations
a) Name the variables:
number of turkey burgers: tnumber of veggie burgers: vb) Number of burgers:
50 = t + vc) Cost of the 50 burgers:
$90 = 2t + 1.50v2. Solve that system of equations:
a) System
50 = t + v90 = 2t + 1.50vb) Mutliply the first equation by 2 and subtract the second equation
100 = 2t + 2v 90 = 2t + 1.50v10 = 0.5vv = 20 ⇒ t = 50 - 20 = 30c) How much would you spend if the next year you buy the double of 20 turkey burgers (40) and the half of 30 veggie burgers (15)
$2(40) + $1.50(15) = $80 + $22.50 = $102.50Then, you if you double the number of turkey burgers, and cut the number burgers in half, you would spend more than $90 ($102.50).

Because 40% of the class is playing games, that means (100-40)% aren't playing, meaning that those 60% haven't finished the assignment.
We find 60% of the total 24 students, and that is .6 * 24 = 14.4
Because you can't have .4 people, the answer rounds (down ) to 14

40% of 24 is 9.6 (Which should be approximated to 10). 24 Students in total - Approximately 10 who have completed the assignment is 14 students who still need to complete the assignment.
The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which answer could represent the mean and standard deviation for these data ?
Answers
Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.

10) Beth and Ming are selling pies for a school fundraiser. Customers can buy blueberry pies and
blackberry pies. Beth sold 3 blueberry pies and 12 blackberry pies for a total of $258. Ming sold
4 blueberry pies and 3 blackberry pies for a total of $110. What is the cost each of one blueberry
pie and one blackberry pie?
Answers
Answer: Each blueberry pie costs $14 and each blackberry pie costs $18.
Step-by-step explanation:
If X is the price of a blueberry pie and Y is the price of a blackberry pie we have that:
3*X + 12*Y = $258
4*X + 3*Y = $110
We have a system of equations, to solve it first we can isolate one of the variables in one of the equations, let's isolate X in the first equation.
3*X = $258 - 12*Y
X = $258/3 - (12*Y)/3 = 86 - 4*Y
now we can replace it in the second equation and get:
4*(86 - 4*Y) + 3*Y = 110
344 - 16Y + 3Y = 110
344 - 13Y = 110
13Y = 344 - 110 = 234
Y = 234/13 = 18
So each blackberry pie costs $18.
And we can replace it in the equation for X and get the value of X.
X = 86 - 4*Y = 86 - 4*18 = 14
So the price of a blueberry pie is $14.
Answer:
the cost each of one blueberry pie is $14
and one blackberry pie is $18
Step by step explanation:
Given that;
Beth sold 3 blueberry pies and 12 blackberry pies for a total of $258.
Ming sold 4 blueberry pies and 3 blackberry pies for a total of $110.
Let x represent the cost of blueberry pies and y the cost of blackberry pie.
3x + 12y = 258 ........1
4x + 3y = 110 ..........2
To solve the simultaneous equations;
Multiply equation 2 by 4, equation 2 becomes;
16x +12y = 440 .......3
Subtract equation 1 from 3;
16x-3x + 12y-12y = 440-258
13x = 182
x = 182/13 = 14
Substituting x=14 to equation 2
4(14) + 3y = 110
3y = 110 - 4(14)
3y = 54
y = 54/3
y = 18
the cost each of one blueberry pie is $14
and one blackberry pie is $18

The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake ?
Answers
Answer:
The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
Explanation:
The magnitude of earthquakes is given by
[tex]Magnitude=log\frac{I}{S}[/tex]
[tex]2=log\frac{I}{S}\\[/tex]
Where I is the intensity of earthquake and S is the intensity of standard earthquake.
The magnitude of standard earthquakes is given by
[tex]Magnitude=log\frac{S}{S}= log(1) = 0[/tex]
So comparing the magnitude of the given earthquake and standard earthquake,
[tex]log\frac{I}{S} = log\frac{S}{S}[/tex]
[tex]log\frac{I}{S} - log\frac{S}{S}[/tex]
[tex]log(2) - log(1)[/tex]
[tex]2 - 0[/tex]
[tex]2[/tex]
which means that
[tex]10^2 = 100[/tex] times greater
Therefore, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
A certain insecticide kills 60% 60 % of all insects in laboratory experiments. A sample of 7 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 4 insects will survive? Round your answer to four decimal places.
Answers
Answer: The probability that exactly 4 insects will survive = 0.2903.
Step-by-step explanation:
Given : The proportion of all insects in laboratory experiments killed by insecticide = 60%=0.60
Since , by using insecticide only two outcomes are possible either it kills or not kills , so we can use binomial.
Sample size of insects = 7
By using binomial probability formula : [tex]P(x)=^nC_xp^x(1-p)^{n-x}[/tex], where x is binomial variable , n = sample size and p is the probability of getting success.
Let x be the number of insects survived.
As per given , we have
n=7 , p=0.60
Now , the probability that exactly 4 insects will survive :
[tex]P(x=4)= ^7C_4(0.60)^4(1-0.60)^3\\\\=\dfrac{7!}{4!3!}(0.60)^4(0.40)^3\\\\= 35\times 0.1296\times 0.064 \\\\=0.290304\approx0.2903[/tex]
Hence, the probability that exactly 4 insects will survive = 0.2903
